Alright folks....I am sure this has been beat to death..

Take a 6spd 99 C5.....stock LS1 intake.

What get's it above 380 rwhp?

I am thinking:
-longtubes (or shortys ok?)
-LS6 intake
-MS3 cam
all the rest stock...with the exception of Blackwing intake filter thingy...and Corsa Extreme catback.

Thanks

(I am trying to decide between N/A or S/C and not really wanting to spend the coin on S/C!)

 

first off, i'd def do long tubes if you're going to do headers.
second, figure out the cost of going n/a's hp gain compared to going s/c'd hp gain, you may find that for just a little bit more on the s/c it will be worth going s/c'd.

personally, according to the dyno i'm currently on, i've gained 90 total with kooks lt's, catted mids, vram and a cam with a good tune.

that is "according" to the dyno i'm using now. most of it comes from the cam. how much did that cost?? not sure and i don't think i want to add it up either.

 

I have over 400 rwhp with LT's and a small cam, but I'm installing a different cam and an A&A SC kit next week....

I'll sale my cam/springs/blackwing intake next week if your interested...


And yes this has been beat to death...

 

Figure out how much ALL this is going to cost you.

Then look at an LS6 or LS2 crate motor. Could be almost the same

 

Yea but neither one will be 400rwhp out of the crate.

 

As mentioned a cam with LTs, CAI, LS6 intake and a tune will get you to 380. Run a bigger cam and you can hit 400. The C5Z puts down around 380 with LT's, CAI, and tune with the small LS6 cam and LS6 heads. With LS1 heads you just need a bigger cam.

 

why would he do that?

 

Those A&A kits make some damn good power - wish I could afford one especially since I'm already H/C/intake but then again I'm still on the stock bottom.

 

No but a small cam in the crate engine will get one there. and still maybe less money then adding everything to an LS1

 

no way that'd turn out cheaper. i'll never understand the old school mentality of using "crate" engines. not for the prices you can have an engine built these days and have better everything.

 

For the price of a crate engine, and a cam, and headers, the OP could have bought a SC kit, and paid for a pro install/tune! In this situation, a crate engine makes NO sense.

 

Your goals are way to simple 400rwhp on a early LS-1 engine.
Yeaa you can get it but it will get expensive and how is your
vette going to run. Will it shake and vibrate have lowsey low
end torque and buck and generally lousey to drive as a DD. All
things to consider. It's more than horsepower and you have to
decide what you want your vette to be. A DD sounds to me like
stock running vette with power. But alot of guys have a different
idea about that. And no body is kidding you this subject is a
very old one with alot of material, so research.

 

stroke it to a 383, small cam, heads and long tubes....

 

I have a "small" cam TSP 228R, and have over 400 rwhp.

Like I said before. If you are interested in a doing this work soon I will sale my 228R cam, Blackwing Intake, PRC Dual Valve Springs, 42 lb Racetonix Injectors, and PowerBond UD Pulley with a new GM Bolt for a deal. All you need are some LT's.

The car drives great and has a choppy idle with it's 112 LSA. All parts have approx 15k miles on them.


It would not make sense to buy a crate motor. If you needed to refresh the bottom end a forged 347ci would be a great foundation for whatever you want to throw at it.

 

Supercharger, headers and catback equal 498.6 rwhp. Add the 3.42 gears to the A4 and WOW.

 

I don't agree and I'm not guessing. I've got over 400rwhp and over 400rwlbft on an "old" LS1 A4, its a DD (82xxx miles) , idles at 800rpm, has a 3.42 and averages 20.6mpg and gets 25.3 highway at a steady 70mph.Its all in the right combo of parts and a good tune.Cost?? It ain't cheap that's for sure!!
